Resistance of Phytohæmagglutinin-treated Lymphocytes to X-rays and Nitrogen Mustard

The normal lymphocyte is highly sensitive to nitrogen mustard (HN2) and to irradiation with small doses of X-rays2. We were, therefore, surprised to find in this work that the derived lymphoblastoid cells are resistant to these reagents.
